Answer:
Step-by-step explanation:
We have been given that vector v has a direction of (5,3). We are asked to find direction angle for v to nearest degree.
We know that direction of vector with components can be determined by
.
Upon substituting the components of given vector in above formula, we will get:
Upon rounding to nearest degree, we will get:
Therefore, the direction angle for vector v is 31 degrees.
Answer:
B. The probability of getting a red convertible is 0.10.
Step-by-step explanation:
Independent events:
Two events, A and B, are independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:
In this question:
Event A: Red car -> 0.25 probability
Event B: Convertible car -> 0.4 probability
Independent if:
The probability of getting a red convertible car is:
Thus, the correct answer is given by option B.
